Problems solved by technology
This results in large image values of the body hair and moles on photoacoustic images to decrease the visibility of observation regions.
However, in the display method discussed in Japanese Patent Application Laid-Open No. 2013-188461, information on an observation region in the surface neighborhood area may also be lost in addition to information about other regions, such as body hair and moles in the surface neighborhood area, that are not the observation regions.

Embodiment Construction
[0019]Various exemplary embodiments, features, and aspects of the invention will be described in detail below with reference to the drawings. Each of the embodiments of the present invention described below can be implemented solely or as a combination of a plurality of the embodiments or features thereof where necessary or where the combination of elements or features from individual embodiments in a single embodiment is beneficial.
[0020]In an image processing method according to a first exemplary embodiment, a position having an image value that is within a predetermined range in photoacoustic image data is determined. Then, the structure present in the position as well as structures present in neighborhood positions are judged unnecessary structures, and a photoacoustic image is displayed. The following describes an image processing method according to a comparative example and the image processing method according to the present exemplary embodiment.
[0021]First, the image proces...

An information processing apparatus includes a first image acquisition unit configured to acquire first image data derived from a photoacoustic wave generated by light irradiation, a position acquisition unit configured to acquire position information indicating a position in the first image data having an image value that is within a predetermined range, a neighborhood position acquisition unit configured to acquire neighborhood position information indicating a neighborhood position neighboring the position based on the position information, and a display control unit configured to cause a display unit to display an image based on the first image data, the position information, and the neighborhood position information.
Description
BACKGROUND OF THE INVENTIONField of the Invention[0001]The present invention relates to an information processing apparatus configured to acquire image data derived from a photoacoustic wave generated by light irradiation.Description of the Related Art[0002]Photoacoustic apparatuses that irradiate a subject such as a living body with pulsed light, and display a photoacoustic image indicating information about the inside of the subject based on an acoustic wave (also referred to as “photoacoustic wave”) generated by photoacoustic effect are known.[0003]In general, body hair and moles on the skin or epidermal layers have a high light absorptive capacity. Thus, photoacoustic waves generated from body hair and moles irradiated with pulsed light are likely to be greater than those produced from other regions of the subject. This results in large image values of the body hair and moles on photoacoustic images to decrease the visibility of observation regions.[0004]Japanese Patent Applicat...
